What we check
Built around the signals Google actually reads.
On-page SEO is the work search engines see on the page itself — the title, the description, the heading outline, the markup. We grade all of it on every URL.
Meta & headings
Titles, meta descriptions, H1 usage and heading hierarchy — the core on-page signals search engines read first.
Social & schema
Open Graph, Twitter card and JSON-LD structured data — so your previews and rich results look the way you want.
Content & links
Missing alt text, thin content, broken canonical references and link patterns that hold a page back.
